[Libreoffice-ux-advise] [Bug 89733] SIDEBAR: Using sliders next to value fields

https://bugs.documentfoundation.org/show_bug.cgi?id=89733

--- Comment #2 from Heiko Tietze <heiko.tietze@user-prompt.com> ---
Sliders are a good means for arbitrary changes within a defined range. To
support accessibility and in order to achieve precise input a spin box is
sometimes appended that not only shows the actual value but allows to modify
it.

We should take care about a consistent implementation. Normally, min and max
should be labeled (not necessary if the range is clear from content but
consistency be respected). It's not recommendable to use non-linear scales (but
often done for zoom; with more labels/tickmarks then). And for an appealing
design it makes sense to have not too many sliders in one dialog/view. 

Jay's and Andy's examples make perfect sense.
